China Defends Iran Theocracy to Protect Energy Interests
China's Defense Minister warns Washington against interfering with Beijing's trade with Iran, exposing Beijing's economic dependency on the Islamic Republic and selective application of its 'non-interference' doctrine.
Chinese Defense Minister Dong Jun warned Washington not to interfere with Beijing's trade with Iran on April 13, declaring "the Strait of Hormuz is open to us" in a confrontation that exposes China's selective application of its "non-interference" doctrine. The warning came hours after U.S. naval forces began enforcing a blockade targeting vessels entering or exiting Iranian ports, creating an immediate standoff that reveals Beijing's economic dependency on the Islamic Republic.
Dong Jun stated, "We have trade and energy agreements with Iran. We will respect and honor them and expect others not to meddle in our affairs." His statement came as Beijing defended its trade interests since the U.S. launched Operation Epic Fury on Feb. 28, striking Iranian military infrastructure and killing Supreme Leader Ayatollah Ali Khamenei. The Chinese position demonstrates Beijing invokes principles of sovereignty only when protecting its own massive financial interests in Iran.
The U.S. naval blockade began at 10 a.m. ET on April 13, targeting all vessels entering or exiting Iranian coastal areas in the Arabian Gulf and Gulf of Oman. President Donald Trump announced the blockade on April 12 after 21 hours of negotiations in Islamabad collapsed, with Vice President JD Vance stating, "I think that's bad news for Iran much more than it's bad news for the U.S."
China's financial stake in Iran is staggering. Beijing signed a 25-year strategic partnership with Tehran in March 2021 committing $300 billion to $400 billion in Chinese investment. China purchases 80 percent to 90 percent of Iranian oil exports, providing Tehran approximately $31.2 billion annually, which constitutes about 45 percent of Iran's government budget.
Beijing's defense of Iran exposes the hypocrisy of its "non-interference" principle. Yet China condemns U.S. actions as "violations of international law" while defending the same regime's control over a critical global shipping lane.
China's energy vulnerability is profound. Approximately half of China's imports flow through the Strait of Hormuz, according to the U.S.-China Economic and Security Review Commission. China imports about 1.4 million barrels per day of Iranian oil, representing 12 percent of total Chinese crude imports.
Iran maintains de facto control over the strait under the ceasefire terms that began April 7 and expire April 21. Vessels must use Iranian territorial waters, pay fees estimated at $2 million per tanker, and accept Iranian naval escort. These are the conditions China now defends as its right to access.
President Xi Jinping proposed a four-point peace framework on April 14 emphasizing "respect for national sovereignty" and "adherence to international law." Xi warned against a "law of the jungle" approach during a meeting with UAE Crown Prince Sheikh Khaled bin Mohamed bin Zayed Al Nahyan in Beijing. The diplomatic proposal provides cover while China's substantive position remains support for Iran's actions.
Trump threatened 50 percent tariffs on China if Beijing supplies weapons to Iran. "If we catch them doing that, they get a 50 percent tariff, which is a staggering amount," Trump told Fox News on April 12. China denies supplying weapons, calling reports "baseless smears and malicious associations."
Chinese tanker Rich Starry transited the Strait of Hormuz on April 14, departing from the United Arab Emirates. The vessel's passage demonstrates China's determination to maintain energy flows through the contested waterway despite U.S. enforcement.
Foreign Ministry spokesperson Guo Jiakun called the blockade "dangerous and irresponsible" on April 14, warning it will "undermine the already fragile ceasefire agreement and further jeopardize safety of passage through the Strait." Guo added, "The Strait of Hormuz is an important international trade route for goods and energy. Keeping the area safe and stable and ensuring unimpeded passage serves the common interest of the international community."
The U.S. Central Command stated neutral transit through the strait to non-Iranian destinations will not be impeded. Fifteen U.S. warships enforce the blockade after Operation Epic Fury destroyed 150 Iranian vessels and approximately 85 percent of Iran's defense industrial base, according to White House statements.
Analysts note China's strategic dilemma. "Beijing's economy remained fundamentally reliant on seaborne exports, and would therefore be vulnerable to an economic downturn resulting from a prolonged closure of the Strait of Hormuz," said Zongyuan Zoe Liu, senior fellow at the Council on Foreign Relations.
China maintains strategic oil reserves estimated at 1.4 billion barrels, enough for four months of total imports.
The confrontation exposes China's energy security as hostage to Iranian decisions about strait access. Beijing defends Iran's right to control the waterway while simultaneously being vulnerable to any restrictions Tehran might impose. China's "peaceful coexistence" rhetoric masks a cynical realpolitik that enables authoritarian regimes when profitable.
The stalemate tests U.S. power projection against a great power ally of Iran. Whether Beijing will risk military confrontation over its Iranian investments remains the central strategic question as the ceasefire approaches its April 21 expiration.
